In general , parms data of proper and improper torsion parameters are
given by 4 coulmns of numbers : IDIVF , PK , PHASE , PN.
However, the parmSet Editor of Xleap gives 3 Columns : N field colum,
PK/IDIV , and PHASE in radians..
It seems that for these reasons , there is always a bug in editing these
parameters (parm94 ) by the the use of editparmset command ...In
particular, it seems that there is a purmutation between N field column
and PK/IDIV column.... Indeed , Operation :"Check the table" shows always
many mistakes , and : Invalid character in N field parameters..
